For anybody alive, ADS gave specific instructions to me about 26 years ago for the L1590 and C-2000. Remove c38 and c39 (size about 6/16 x 7/16 x 2/16 inch, color redish brown, marked ".1k 50/100"). The cross over selector is set to prog. and the crossover program switches in the back are set so each switch (the little circular hole in each switch) is at the bottom position. Before the removal described, this configuration provides the 300 Hz crossover and 0.68 filter Q. There are 15 other combinations of switch settings possible. If this is relevant to you, I would appreciate your response
Can ADS C2000 X-over be modified for L1590 spkrs?
Does anyone out there know what the modifications are to make the ADS C2000 Biamp X-over work on the L1590's? This x-over was originally set-up for the ADS L1230/1530/2030, but could be modified to work on the L1590's; I believe two capicators had to be removed, and the program switches on the back were to be activated, but can't remember the positions. ADS is absolutely no help now, all people who knew about this are gone. Help!
